Storage virtualization has been proven to reduce many different types of storage related costs. Most notably the costs of migration, asset purchase, cost of waste, floor space, electricity and many others are reduced with controller-based, heterogeneous storage virtualization. When building a business case to move to a virtual, flexible, content-and-information-cloud architecture, these cost areas are [...]
My one key message (for the past 12 years) is that cost reduction is not accidental; it takes a determined and structured approach. I have simplified the process to be 3 steps: identify, measure and reduce. Some previous blog entries on these topics are here:
The past 3 blogs have covered the economics behind reclamation (of disk) compared to buying new disk. My material has focus on reclamation due to storage virtualization, over provisioning (thin provisioning) and zero page reclaim. The same methods can be used for other capacity efficiency techniques to be sure. The other blogs covering the setup, [...]
This is my 3rd installment of a 4-part series on when/how it is cheaper to reclaim disk as opposed to buying new. The previous 2 entries covered the setup and calculations, now we will look at conditions when each tends to be better.
My previous blog entry discussed the opportunity of deciding if it is cheaper to reclaim (poorly utilized) disk compared to purchasing net new disk. This blog entry will setup how to calculate a simple reclaim vs. buy analysis.
Disk prices are rising. I hope I am not the bearer of bad news, but you have probably heard, or seen for yourself, that recent natural disaster and supply problems have caused some disk prices to rise. This is not good at a time when (for most) there is still pressure on CAPEX. Unless you [...]
Ever since we started decentralizing IT resources in the golden-era of client/server (mid-90s), we have been working to reign in the sprawl by consolidation recommendation. As soon as we consolidate, there will be another reason to sprawl (perhaps next time in someone else’s cloud infrastructure). Consolidation has been an effective technique for many years to [...]
